Gas Heater 6v in 12v vehicle

the soution is very simple. Wire the fan and igniter in SERIES (instead of
||), and it will work fine on 12V. BTDT. Take the ground from the fan, and
run it to the input of the igniter. Since each device draws around the same
current, you'll get 6V across each. I have done this for years.
